To all 'wlw/n it may concern Be it known that I, DOWLINGBENJAMIN,

,a citizen ofthe United States, residinsg at tate :iniLa-nti-freeze liquid.

condition iu all suchradiators,l however, is not attained or nmintained when the auto-ff, .mobile is in use, for. the 'reason that there Camden, in the county of Camden and of New Jersey, have invented certain new and useful Improvements in Condensing` Radiators, of which the following is a speri feation.

- Automobile radiators are usually con structed solely for the purpose of cooling the 4Water, or other fluid which is used in all water cooled automobile engines, the'idea being to practically keeptlie radiator filled with water. To Secure the omplete filling of the nuliatorand also to keep Tthe radiator chamber freely open tothe atmosphere,

tlurii is necessarily provided an loverflow pipe which' entends entirely to the' topof the radiator,V the object beingr to keep the radiator full of Water or mixture of Water This desired ideal is u constant loss ot' -the fluid through the overflow pipe by evaporation, expansion of fluid by heat.' audsplash and spill of the Huid through the overfiow pipe due ,to the motion of the' ear caused by irregularities ot' the road and vibration. The result of these conditions. therefore, inevitably causes in a short'tinie the formation of'a vacant space at the top of the radiator which in creases in size :is time goes on until the radiator-,if not constantly refilled, becomes ab Solutely empty-causing injury to the engine.' This .latter condition occurs ery 'quickly if .the temperature of the-Huid rljraehes the boillng point.

v'l`heiuain objectof my ilnvention is to' ti'on so thntfit will normally he operative whileolosed to the atmosplure.

.\ further object is to providelnv inveninvention with a condensing hea vin -seetion tion with means for. regulating the internal'lpressure proportionately to the atmosf pherl pressure.

A still further object is to V rovicle my which is so located and constructed that the' va or enteringthe same will be automatieal y ke t moving-into `contact therewith due to tie splash of the cooling fluid and variation of the level of thecooling lluidin the radiator'y said variation being eausedby the niotionof the automobile.

. Anotlieiobject ofV my invention is to provide means whih will effectively cerny oft' the heat of the water or otherpooling Huid which -is used to keep the engine cylinders'eool.

:Ystill'further object is to so design my invention that it will be of comparatively simpleconstruction and can be readily attaehed'or removed.

A sti-ll further object is to so olesign'm5r invention that it willbe of 'simple construe` tion and can he 'readily attachedto or r e' moved from automobilesof various types.

'lhese objects, and vother advantageous ends whichwill he described hereinafter, l attain Vin'the `following manner, reference being luid'to the accompanying draw` 'ings n1 wluch- Figure. 1 is it frontelev'ation of a combined Avapor condenser and radiator -eonstructed in accordahee-with my invention.

Referring to the drawings, 14 re resents.-

the tank through which circulates t e cooling' fluid for the engine c linders. This `ing illustrated in the tank in the present instance ias a fllin inlet illustrated in the formof a pipe 2 w ich, i0

usual hood 4. l Pipes 5 and 6 connect with a receptacle 4in the foi'nilof a tank 1 and form the circulating means between the -tank and the usual water jacket of the en ine, the latter not berawing.

The tank 1 is open at the top as shown at 7 and has an inturriedV flange 8 which forms a ledgeor seat for a vapor-condensing head 9. It will be noted that the Afilling pipe 2 enters the tank 1 at a point below the Vaporcondensing head 9 so that it is impossible to overill said' tank.i Thus tlie.vaporcon (lensing head 9 isl kept free of the coolingis closed with a cap 3 and located under the fluid when the automobile is not in motionA '8 of the tank 1. he bolts or rivets 26 pass but is permitted to splash therein, as will explained hereinafter, when the automobile is in motion. In Figs. 1 to 7 inclusive, this head includes a hollow jacket 10 which com-- prises two sections 11 Aand 12. The section 11 consists of a' recessed casting having two p substantially vertical extensions 13'and 111m, ,4 and a horizontal portion 15.. Theisection 11) has integral langes 1G beth front and back,' and the flanges at the 'inner edges and bot tems of the vertical extensions 13 and 14 and attlie bottom edges of the portion 15 form means for the attachment. of the section 12 which in the present instance consists of a plate of sheet metal bent in theorr'n illustrated.

The flanges 16 of the section 11 ma. be

secured to the section 12 by rivets as ilustrated or by any other suitable'nieans such for example as electric or spotA weldin The section 12 is preferabl)r inade of a pla of sheet metal and extends from front to back and thus the recess 'in the section 11 forms a chamber 17 which extends throughout the length of the extensions 13"imd I14 and lthe horizontal portion l5. '.Ifhe section 1 2V at its extreme bottoni is bent under the extensions 13 und 14, as illustrated at 18 (see Fig. T), and rivets or bolts 2G extend thiou 7hutlie bottom flanges of the extensions 13 an 14. Y,

A base plate 19 extends directly' under the jacket 10 and under the portions 18 of'the Sectioml, and this plate l!) and the horizon tal poition 24) of the sect-ion l2 have slots 21 and respectively arranged 4in vertical alinement. A plurality of, hollow plates 23 whioh'are pirferabl)- made of flattened tubes, extend between the plato l!) and portion 20 of the section 12 therop'posite ends of said hollow plates extending respectively through the also to secure the hollow plates in position.

The ends of said hollow plates are open so as to establish communication between the-interior of the tank 1.and the chamber 17. The slots 21 and 22 a-i'earranged at an 75 angle so that the hollow plates 23 when secured in position, will also' be disposed at an angle as clearly shown in Fig. 4 for a purpose hereinafter described.

The base plate 19, adjacent its opposite end, isp'rovided with holes 24 through which extend sleeves 25 which may be formed 'by punching the portions 18 of the section 12 downwardly as clearly shown in Fig. 7, said sleeves also forming perforations or holes g5', within said portion 18, so that the portion of the chamber 17 which extends within the extensions 13 and 14 is also in communication with' the interior of the tank 1.

The base filato 9 also rests on the flange through the flangesi 16 of the section 11, the

'portion 18 of thesection 12, the base plate '19, and the flange .8 of the tank 1, thus se curing `the head 9 to the tank 1- and per- 95 initting said head to be readily removed VZfrom"the tank and also permitting the sccrecessed casting1 2 7l and' a sectionV 28,of isheet .1 o 5 tion of saicbsection 27...' v ,p i

In this instance the hollow lates extend directly throurh slots 29 in t e section 2 and through t ie slots 30 in a. base plate 31, 11o the latter corresponding to the hase plate 19 above described. In all other respects the construction is similar to that described in material is'rsecuretl-to :the-outer flanged' or;

connection with Figs. 1 to 7 inclusive und 1 parts coliehave therefore given similar sponding reference numerals.

In, Figs. 1l) to 12 inclusive, l have illus trated the pressure compei'isatngr portion of.

`my invention, the description of the same A sleeve 556 has its lower ond 2li' ruw- '-threaded and designed to lit within the in .'ternally screw-threaded portion :l5 of thc annular fpmre :53. A cover plate 3H has a depending ange 39 which is internally 13 0 screw-threaded and designed to engage the upper screw-threaded end 40.. of the sleeve V36. The sleeve 36 i'sprovided with taperedl openings 41 and 42, the opening-41 tapering the inner surface of the sleeve 36. The va'lve 44 isheld upon its seat by a spring 47 which `in turn is backed b i a bridge 48 secured to 'the outer surface-o the,sleeve 36. 4

A cap 49 has an internally lscrew-threaded bottomedge portion lll'which lits `the externally screw-threaded portion 34 of the an-l nular flange'. 33.' This cap 49 isof larger diameter than the sleeve 36 and forms 'a housing therefor. i

` The cap -49 is perforated at liand these.

perforations communicate withthe space 52 located between the inner surface o f the cap 49 and the outersurface of the sleeve 36.V vIt will thus be understood that any vpressure that is formed within the chamber 17 ,will

be compensated for by the valve's43 and 44.. For exa'mple,' if l the pressure within the chamber- 17 becomes greater than th'e resist-v -ing 'power of the spring 47, the valve 42 will be forced outwardly `to relieve the pressure', 4and the valve 44 .will remain open until tliepressure, witliii the chamber 17 and con-4` sequently, witliin Athe tank' 1 is reduced'. On-

the other hand, the pressure within the chamber 1T is. greatly reduced, the valve 43 will be opened' by pressure outsi'de of 'sleeve 36 and thereby compensate for the difference between the external and internalpressure.

'llo guard againstthe malicious removal of the cap 49, I provide the latter with a lock 53 which may be 'of any of the well known types such for eiample as Yale or- (Jorbin, so that no' on'e but an authorized person can remove the cap 49. 4 4 In the usc of my invention, the movement of the automobile du'ring its pro ess willcause the water or. cooling Huid 4 lwithin the tank l to frequently splash upwardly through the hollow plates 23, causln plates, and'sincc the latter are spacedapart and have their outer surfaces 'exposed to. the

atmosphere, said vap'ol: 1s condensed and.

runsback into the tank 1 and splash water 54 will also be cooled and will fall back into 0011*' stant circulation of the vapor throug vthe foi .sleeves 2510 thetank .1, same as the con- -densed vapor.

f extremely cool` when the automobile islfn motion. Anyevapor which is formed within i the 'tank 1,` will rise' through the hollow plates ,and by coming into contact there with and with the lnnersurface of the jacket 10, will be moved by the splash of the cooling-fluid and by. the movement of the automobile -and thus will be quickly condensed into liquid form and return to the tank 1. i

It will' ums be; understood that ivan the empio ient of my invention on an autonioi bile, t e cooling fluid for' the engines can be kept effectively cool and the vapor will be quicklycondensed', thereby preventing lossA -of thes cooling 4Huid sin'ce thereLis n o overflow pipe necessary and the radiator is prac'l v'tically closed; .thus avoiding evaporation .or the spilling of the cooling fluid. Also by -the construction and arrangement ofpthe parts of -m inventionthe vapor will be' agitated 'an circulated through the condens ing head,jas above described, and the c001- ing Huid will-'be kept in motion. Thus the possibility "of scaling of the several parts is Vreduced to a minimum.

By having -the construction above set forth, I am enabled automatically and constantly. tol supply the radiator with the proper amount of distilled AWater. The advantage thereby attained is that thereis no possibility` df incrustationo'r chemical action upon the interior of the water cooling system for'the reason thatthere is no concentration o' mineral contents of the water 'by eyaporation and for the. reason that there is no necessity for adding water as 1s necessary in thel radiators made prior to my invention. This is an important advantage since it is wellknown that al] natural waters except distilled water contain mineral constituents which minerals, if the water is allowed to evaporate.4 form crystals lon theintcrior of the radiator, thereby injuring the saule so as to impair the' proper. functioning of the parts. .A

Also by. uy present invention I .am enabled, when antiffreeze solutions are 'used which are composed of chlorids" and other chemicals, td prevent the concentration of t Acse solutions by loss ofthe Water which lu dstheminsolution.l Ithus preserve the uninormal specific -gravity or strength of the Aanti-freeze `solution employed, thereby preventing concentration and chemical action as above noted. Furthermore, bythe use of my inveution.- l am enabled when a mix#l turc of alcohol and Water is used for an antilfreeze solution to preserve the percentage of water and alcohol in their proper roportions one to the other, Owing to t e fact that alcohol evaporates faster than water, it is obvious that without this construction the ercentage of alcohol and water would rapidly chan until the contents of a radiator would a most be deprived of its rop- 'erties or its' ability toact as an antireezc imxture.

. a tank, it will be understood that any form taking a particular form,

of a receptacle may be used in lieu thereof` it being suiiicient to state that any form of receptacle may be used as a support for or above which the head 9 is mounted.

Vhile I have described my invention as` it will be understood hat the,various parts of my invention may be changed without departing from the spirit thereof, and hence I do notlimit myself to thev precise vconstruction set forth, but consider that I am at liberty to make such changes and alterations as fairly come within the Iscope of the appended claims.
